Rotary directional pressure engine

A non-interference rotary directional pressure engine with no compression stroke, comprising:

• a substantially sealed case having a rotor section and a gear section;
• at least one intake port and at least one exhaust port passing through a wall of the case;
• a plurality of non-contacting rotors adapted to rotate in parallel within rotor wells located in the rotor section of the case and without contact therewith, each rotor coupled to a shaft that extends from the rotor section into the gear section and rotates with its associated rotor;
• an asymmetrical cavity located on the circumferential face of each rotor, the asymmetrical cavities shaped and located on the rotors so as to become periodically aligned during rotation to form, along with interior walls of the case, a substantially sealed combustion chamber;
• at least one ignition device protruding into the combustion chamber for igniting an air-fuel mixture located therein;
• intermeshed timing gears located within the gear case, a timing gear associated with each rotor shaft that extends into the gear case;
• at least one pair of intermeshed drive gears located in the gear case and associated with a corresponding number of like-rotating rotor shafts;
• an output gear intermeshed with the drive gears;
• and
• an output shaft coupled to the output gear for rotation by rotational movement of the rotors.

A non-interference rotary directional pressure engine having only an intake stroke, a combustion stroke, and an exhaust stroke, comprising:

• a substantially sealed case having a rotor section and a gear section;
• a plurality of intake ports passing through different walls of the case, the intake ports located such that air or other gases entering the case through the intake ports will be caused to collide within the combustion chamber;
• at least one exhaust port passing through a wall of the case;
• a plurality of non-contacting rotors adapted to rotate in parallel within rotor wells located in the rotor section of the case and without contact therewith, each rotor coupled to a shaft that extends from the rotor section into the gear section and rotates with its associated rotor;
• an asymmetrical cavity located on the circumferential face of each rotor, the asymmetrical cavities shaped and located on the rotors so as to become periodically aligned during rotation to form, along with interior walls of the case, a substantially sealed combustion chamber;
• at least one ignition device protruding into the combustion chamber for igniting an air-fuel mixture located therein;
• a combustion force deflector centrally located within the combustion chamber and without interference between the rotors, the deflector being shaped and orientated so as to redirect forces of combustion toward the most advantageous fulcrum points of the rotors;
• intermeshed timing gears located within the gear case, a timing gear associated with each rotor shaft that extends into the gear case;
• at least one pair of intermeshed drive gears located in the gear case and associated with a corresponding number of like-rotating rotor shafts;
• an output gear intermeshed with the drive gears;
• and
• an output shaft coupled to the output gear for rotation by rotational movement of the rotors;
• wherein, the asymmetrical cavities located on the circumferential faces of each rotor are also shaped to move intake air toward the combustion chamber during an intake phase of the engine and to move gases of combustion from the combustion chamber toward the at least one exhaust port during an exhaust phase of the engine.
